The Global Status Report for Buildings and Construction (Buildings-GSR) is a flagship publication of the UNEP-hosted Global Alliance for Buildings and Construction (GlobalABC). The Buildings-GSR provides an annual snapshot of the progress of the buildings and construction sector on a global scale and reviews the status of policies, finance, technologies, and solutions to monitor whether the sector is aligned with the Paris Agreement goals. It also provides stakeholders with evidence to persuade policymakers and the overall buildings and construction community to take action.

What is new in the 2022 Buildings-GSR

  • Buildings and construction: disruptions and challenges facing the buildings sector in 2022 
  • Global Building Carbon Tracker: Are we on track towards the Paris Agreement Goals?
  • Updates on building codes and building decarbonisation in Nationally Determined Contributions (NDCs)
  • Status of investment in building energy efficiency
  • Deep dive on:
    • Africa (regional focus)
    • Building materials (topical focus)

The 2022 Buildings-GSR finds that 

  • Despite a substantial increase in investment and success at a global level lowering the energy intensity of buildings, the sector’s total energy consumption and CO2 emissions increased in 2021 above pre-pandemic levels. Buildings energy demand increased by around 4% from 2020 to 135 EJ – the largest increase in the last 10 years. CO2 emissions from buildings operations have reached an all-time high of around 10 GtCO2, around a 5% increase from 2020 and 2% higher than the previous peak in 2019. 
  • The buildings and construction sector is not on track to achieve decarbonization by 2050. And the gap between the actual climate performance of the sector and the decarbonization pathway is widening.
  • Global energy price volatility and rising interest rates are likely to hamper investment in building decarbonization by governments, households, and businesses.

Cities need to take a systems approach if they are to develop urban infrastructure that will achieve net-zero carbon and climate-resilience goals. This report focuses on such a systems approach at the urban scale. Cities are responsible for more than 70% of global carbon dioxide emissions, with transport and buildings being among the largest contributors. Cities will also feel the greatest impact from climate change, with 70% of the global population predicted to be living in urban areas by 2050, and 95% of this urban expansion set to take place in the developing world. The report outlines case studies that provide in-depth explanation of how net-zero carbon strategies and infrastructure for climate resilience can be developed by involving all stakeholders, from companies and public institutions to the general public.

Accounting for nearly 40% of global CO2 emissions and sometimes as much as 70% in large cities, buildings and construction are central to the low-carbon transition. Decarbonising buildings, especially the old stock, through energy efficiency improvements and renewable energy use, not only reduces carbon emissions, but also generates co-benefits in health, energy affordability and the labour market. Additionally, global mega-trends and the transition to a green recovery from COVID-19 provide impetus for stakeholders to take action. Cities and regions have a key role to play and can leverage prerogatives in regulation, public procurement and stakeholder engagement, while addressing multiple governance, capacity and funding gaps. To accelerate and scale up their action, cities and regions need to work with national governments to create an effective governance mechanism. Drawing on the findings of a dedicated survey of cities and regions of all sizes from both OECD and non-OECD countries, this report explains their significant role, explores sub-national policy measures, identifies key obstacles, and provides policy recommendations and a checklist for both national and subnational governments to drive the decarbonisation of buildings in cities and regions.

Buildings – our homes, schools, offices - are at risk from extreme climate events such as floods, storms, heatwaves, droughts, soil erosion or wild fires. Developing countries and poorer populations, which are more exposed and more vulnerable to disasters, are disproportionately affected by climate change. Among the 100 fastest growing cities in the world, 84 are already at an extreme risk from climate change. Failure to adapt buildings can threaten socio-economic development. Yet, adaptation of the building sector remains largely unaddressed.

PEEB’s new briefing, the Adaptation imperative for Buildings, demonstrates the importance of implementing climate adaptation and mitigation in tandem to address current climate threats and avoid worst future impacts. Synergies between mitigation, adaptation and development goals in the building sector are numerous: passive cooling, flexible design, local materials, nature-based solutions or water conservation can both improve the resilience of buildings and reduce their environmental impact while increasing quality of life and local employment. These synergies must be brought to wider global attention in order to scale up action.

With over 10% of all investments worldwide, development banks can play a major role in scaling up low-carbon and resilient buildings by raising awareness, setting new standards and building capacities. The briefing presents a set of recommendations and case studies to help development banks mainstream climate adaptation and mitigation across their investments in partner countries.

The Global Status Report for Buildings and Construction is a reference document published by the UN Environment Programme (UNEP)-hosted Global Alliance for Buildings and Construction (GlobalABC). This year's edition finds that in 2020, the sector accounted for 36 per cent of global final energy consumption and 37 per cent of energy related CO2 emissions, as compared to other end use sectors. While the level of emissions within the sector are 10 per cent lower than in 2019, reaching lows not seen since 2007, this was largely due to lockdowns, slowing of economies, difficulties households and businesses faced in maintaining and affording energy access and a fall in construction activity. Efforts to decarbonize the sector played only a small role.

Global Energy and Emissions 2021 Buildings GSR

Collectively, stakeholders in the sector must seize the opportunity that the COVID-19 economic recovery period offers to foster transformation for decarbonizing the sector. The sector must simultaneously meet a projected near-doubling of global demand for energy services in buildings and at least a doubling of floor space as developing economies continue to respond to the growing demand for building floor space, access to energy services and economic activities.

This report looks in detail at the results of six whole life cycle assessment (WLCA) case studies to illustrate some of the challenges, barriers and opportunities relating to the building industry’s carbon footprint. It aims to provide an insight into the industry’s current performance and compare it to possible net-zero trajectories.

Analyzing the whole life carbon emissions of six building projects using the WBCSD Building System Carbon Framework, the report shows that:

  • An average whole life carbon footprint of 1,800 kgCO2e/m2 was estimated across the six case studies.
  • As much as 50% of whole life carbon emissions in a building comes from embodied carbon (manufacturing of materials and the construction process) the majority of this being emitted immediately at the start of the life cycle.
  • Typically as few as six materials account for 70% of the construction-related embodied carbon.

The report identifies crucial next steps to support the sector’s journey toward decarbonization:

  • Adopt a clear definition of a net-zero building, taking into account whole life-cycle carbon.
  • Carry out WLCA on all projects, using a consistent methodology and open-source sharing of the data obtained.
  • Commit to clear, simple global targets across the buildings industry, including a valid approach to residual emissions (offsetting).
  • Develop consistent and transparent carbon intensity certification for components, systems and materials used by the industry.
  • Achieve wider collaboration as individual organizations taking action is not enough.

WBCSD developed this report in collaboration with professional service firm Arup. The authors encourage stakeholders from across the built environment to conduct whole-life carbon assessments of their projects and openly publish the results to create a body of evidence and foster shared learning.
